核医学科放射性污水设计停留时间探讨

Discussion on Design Delay Time of Radioactive Sewage in Nuclear Medicine Department

国家现行污水排水排放标准中对核医学科放射性污水排放要求并不一致,根据不同的排放要求,结合对核医学科常用的同位素,以及设计排水量等相关参数的分析,对衰变池采用的设计停留时间这一关键参数进行了对比计算,并给出了建议。

The current national wastewater discharge standards have different requirements for radioactive wastewater discharge from nuclear medicine. According to the different emission requirements, combined with the analysis of the commonly used isotopes in nuclear medicine, and the design discharge and other relevant parameters, the key parameter of the design residence time used in the decay pool is calculated and compared, and some suggestions are given.
